Harmonic Highlights:
- Extensive use of altered dominant voicings and extensions, including #5, #9, and b9, enriching tension and resolution.
- Sequential ii-V progressions frequently modulate through distant keys, notably descending by major thirds or minor thirds (e.g., F to Bb, Eb, then Db via V7s).
- Prominent secondary dominant functions, such as E7#5#9 serving as V/vi leading to Am7.
Improvisation Focus: Altered dominant scales and chromaticism for navigating rapid, complex ii-V modulations.
Difficulty Rating: 5 (Advanced). The rapid, altered ii-V modulations to harmonically distant keys demand high harmonic sophistication and quick adaptation.
